Blogs are everywhere. Blogs make it easy for anyone to publish to the web. They can help you write, think, process, analyze, and collaborate. Read a few. Pay attention to the "blogrolls", comments, and links. Those that use blogs in the classroom see a real value in using them because it promotes reflection, promotes analytical thinking, gives students voice, motivates them by giving them a larger audience, and promotes collaboration.
